If the pigpio daemon is running it should be killed (sudo killall
pigpiod) before make install and restarted afterwards (sudo
pigpiod).<br>
<br>
<span style="font-weight: bold;">The initial part of the make, the
compilation of pigpio.c, takes 100 seconds on early model
Pis.&nbsp; Be patient.&nbsp; The overall install takes just over 3
minutes.</span><br style="font-weight: bold;">
<h3>Download and install latest version<br></h3>
<code>
wget https://github.com/joan2937/pigpio/archive/master.zip<br>
unzip master.zip<br>
cd pigpio-master<br>
make<br>
sudo make install<br>
</code>
<br>
If the Python part of the install fails it may be because you need
the setup tools.<br>
<br>
<code>sudo apt install python-setuptools
python3-setuptools<br></code><br>
<br>
<h3>To check the library</h3>
These tests make extensive use of GPIO 25 (pin 22).&nbsp; Make sure
nothing, or only a LED, is connected to the GPIO before running the
tests.&nbsp; Most tests are statistical in nature and so may on
occasion fail.&nbsp; Repeated failures on the same test or many
failures in a group of tests indicate a problem.<br>
<code><br>
sudo ./x_pigpio # check C I/F<br>
<br>
sudo pigpiod&nbsp;&nbsp;&nbsp; # start daemon<br>
<br>
./x_pigpiod_if2 # check C&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; I/F to
daemon<br>
./x_pigpio.py&nbsp;&nbsp; # check Python I/F to daemon<br>
./x_pigs&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; # check
pigs&nbsp;&nbsp; I/F to daemon<br>
./x_pipe&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; # check
pipe&nbsp;&nbsp; I/F to daemon<br>

<h3>To compile, link, and run a C program</h3>
<code>gcc -Wall -pthread -o foobar foobar.c -lpigpio -lrt<br>
sudo ./foobar</code><code><br></code><br>
<h3>To start the pigpio daemon<br></h3>
<code>sudo pigpiod<br></code>
<h3>To stop the pigpio daemon<br></h3>
<code>sudo killall pigpiod<br></code><br>
<h3>github</h3>
<code>git clone https://github.com/joan2937/pigpio</code><br>
<h3>Raspbian (raspberrypi.org image)</h3>
<p>This may not be the most recent version.&nbsp; You can check the
version with the command pigpiod -v.<br></p>
